2025-01-24Merge tag 'nand/for-6.14' into mtd/nextMiquel Raynal
* Raw NAND changes A new controller driver, from Nuvoton, has been merged. Bastien Curutchet has contributed a series improving the Davinci controller driver, both on the organization of the code, but also on the performance side. The binding has also been converted to yaml, received a new OOB layout and now supports on-die ECC engines. The Qualcomm controller driver has been deeply cleaned to extract some parts of the code into a shared file with the Qualcomm SPI memory controller. Aside from these main changes, the Cadence binding has been converted to yaml, the brcmnand controller driver has received a small fix, otherwise some more minor changes have also made their way in. * SPI NAND changes The SPI NAND subsystem has seen a great improvement, with the advent of DTR operations (DDR operations, which may be extended to the address cycles). The first vendor driver to benefit from these improvements is the Winbond driver. A new manufacturer driver is added SkyHigh, with a new constraint for the core, it is impossible to disable the on-die ECC engine. A Foresee device is also now supported.

2025-01-23drm/v3d: Assign job pointer to NULL before signaling the fenceMaíra Canal
In commit e4b5ccd392b9 ("drm/v3d: Ensure job pointer is set to NULL after job completion"), we introduced a change to assign the job pointer to NULL after completing a job, indicating job completion. However, this approach created a race condition between the DRM scheduler workqueue and the IRQ execution thread. As soon as the fence is signaled in the IRQ execution thread, a new job starts to be executed. This results in a race condition where the IRQ execution thread sets the job pointer to NULL simultaneously as the `run_job()` function assigns a new job to the pointer. This race condition can lead to a NULL pointer dereference if the IRQ execution thread sets the job pointer to NULL after `run_job()` assigns it to the new job. When the new job completes and the GPU emits an interrupt, `v3d_irq()` is triggered, potentially causing a crash.

2025-01-23PCI: Batch BAR sizing operationsAlex Williamson
Toggling memory enable is free on bare metal, but potentially expensive in virtualized environments as the device MMIO spaces are added and removed from the VM address space, including DMA mapping of those spaces through the IOMMU where peer-to-peer is supported. Currently memory decode is disabled around sizing each individual BAR, even for SR-IOV BARs while VF Enable is cleared. This can be better optimized for virtual environments by sizing a set of BARs at once, stashing the resulting mask into an array, while only toggling memory enable once. This also naturally improves the SR-IOV path as the caller becomes responsible for any necessary decode disables while sizing BARs, therefore SR-IOV BARs are sized relying only on the VF Enable rather than toggling the PF memory enable in the command register.

2025-01-23pwm: microchip-core: fix incorrect comparison with max periodConor Dooley
In mchp_core_pwm_apply_locked(), if hw_period_steps is equal to its max, an error is reported and .apply fails. The max value is actually a permitted value however, and so this check can fail where multiple channels are enabled. For example, the first channel to be configured requests a period that sets hw_period_steps to the maximum value, and when a second channel is enabled the driver reads hw_period_steps back from the hardware and finds it to be the maximum possible value, triggering the warning on a permitted value. The value to be avoided is 255 (PERIOD_STEPS_MAX + 1), as that will produce undesired behaviour, so test for greater than, rather than equal to.

This is much simpler and more efficient. - Convert some users such as ext4 to use the CRC32 library API instead of the crypto API. More conversions like this will come later. - Add a KUnit test that tests and benchmarks multiple CRC variants. Remove older, less-comprehensive tests that are made redundant by this. - Add an entry to MAINTAINERS for the kernel's CRC library code. I'm volunteering to maintain it. I have additional cleanups and optimizations planned for future cycles. * tag 'crc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux: (31 commits) MAINTAINERS: add entry for CRC library powerpc/crc: delete obsolete crc-vpmsum_test.c lib/crc32test: delete obsolete crc32test.c lib/crc16_kunit: delete obsolete crc16_kunit.c lib/crc_kunit.c: add KUnit test suite for CRC library functions powerpc/crc-t10dif: expose CRC-T10DIF function through lib arm64/crc-t10dif: expose CRC-T10DIF function through lib arm/crc-t10dif: expose CRC-T10DIF function through lib x86/crc-t10dif: expose CRC-T10DIF function through lib crypto: crct10dif - expose arch-optimized lib function lib/crc-t10dif: add support for arch overrides lib/crc-t10dif: stop wrapping the crypto API scsi: target: iscsi: switch to using the crc32c library f2fs: switch to using the crc32 library jbd2: switch to using the crc32c library ext4: switch to using the crc32c library lib/crc32: make crc32c() go directly to lib bcachefs: Explicitly select CRYPTO from BCACHEFS_FS x86/crc32: expose CRC32 functions through lib x86/crc32: update prototype for crc32_pclmul_le_16() ...

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI updates from Rafael Wysocki: "The most significant change here is replacing msleep() in acpi_os_sleep() with usleep_range() to reduce spurious sleep time due to timer inaccuracy which may spectacularly reduce the duration of system suspend and resume transitions on some systems. All of the other changes fall into the fixes and cleanups category this time. Specifics: - Use usleep_range() instead of msleep() in acpi_os_sleep() to reduce excessive delays due to timer inaccuracy, mostly affecting system suspend and resume (Rafael Wysocki) - Use str_enabled_disabled() string helpers in the ACPI tables parsing code to make it easier to follow (Sunil V L) - Update device properties parsing on systems using ACPI so that data firmware nodes resulting from _DSD evaluation are treated as available in firmware nodes walks (Sakari Ailus) - Fix missing guid_t declaration in linux/prmt.h (Robert Richter) - Update the GHES handling code to follow the global panic= policy instead of overriding it by force-rebooting the system after a fatal HW error has been reported (Borislav Petkov) - Update messages printed by the ACPI battery driver to always refer to driver extensions as "hooks" to avoid confusion with similar functionality in the power supply subsystem in the future (Thomas Weißschuh) - Fix .probe() error path cleanup in the ACPI fan driver to avoid memory leaks (Joe Hattori) - Constify 'struct bin_attribute' in some places in the ACPI subsystem and mark it as __ro_after_init in one place to prevent binary blob attributes from being updated (Thomas Weißschuh) - Add empty stubs for several ACPI-related symbols so that they can be used when CONFIG_ACPI is unset and use them for removing unnecessary conditional compilation from the ipu-bridge driver (Ricardo Ribalda)" * tag 'acpi-6.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: APEI: GHES: Have GHES honor the panic= setting ACPI: PRM: Fix missing guid_t declaration in linux/prmt.h ACPI: tables: Use string choice helpers ACPI: property: Consider data nodes as being available media: ipu-bridge: Remove unneeded conditional compilations ACPI: bus: implement acpi_device_hid when !ACPI ACPI: bus: implement for_each_acpi_consumer_dev when !ACPI ACPI: header: implement acpi_device_handle when !ACPI ACPI: bus: implement acpi_get_physical_device_location when !ACPI ACPI: bus: implement for_each_acpi_dev_match when !ACPI ACPI: bus: change the prototype for acpi_get_physical_device_location ACPI: fan: cleanup resources in the error path of .probe() ACPI: battery: Rename extensions to hook in messages ACPI: OSL: Use usleep_range() in acpi_os_sleep() ACPI: sysfs: Constify 'struct bin_attribute' ACPI: BGRT: Constify 'struct bin_attribute' ACPI: BGRT: Mark bin_attribute as __ro_after_init
